I have to replace the output seal on my 247 transfer case and want to make sure i do it right the first time.
most people recommend the mopar seals over others and other parts stores have them listed odd or wrong. i believe the mopar part number is 4897298AA for the 247 SEAL OUTPUT SHAFT.
i have gathered this is the correct way to do it. correct me if i am wrong
1) drive the rear of jeep up on a ramp and chock the front tiers
2) put on the parking break on, because I will have to remove the rear drive shaft and "park" does not work when the drive shaft is disconnected.
3) Drain transfer case fluid
4) mark the line across the pinion yoke so it will be installed right later, then Remove rear drive shaft and slide it out of the t-case output. oil might leak out so keep a oil pan near by and keep the TC output shaft for getting dirty or damaged.
5) The old seal is now exposed. Hook it with a "seal puller" tool and pry it out of there. Careful you are prying on the seal and not digging into the aluminum inside the housing. It should come out somewhat easily.
6) Tap the new seal in place. You can do this easily with just a rubber mallet and block of wood
7) Re-install drive shaft. Careful there is no dirt on the surface that is to seal with the t-case.
8) fill the TC with new fresh fluid
-how heavy will the drive shaft be?
since i will be on my back, should i consider putting a jack stand under it just for help?
- will these work for step 5?

- if not anyone have another method for removing the seal?
like with a screwdriver or pliers
- in step 6 when using a block of wood, the wood has to be thin enough to go into the output shaft correct?
- when installing the shaft going into the TC can it go in wrong or is there no wrong way?
i know when connecting DS to the rear it has to be installed in the same way i removed it.
- this should be an hour job max right
thanks for your time and have a few pics below

and these is the how to for removing the drive shaft, this is simple
and this is the how to for the seal the special tools are throwing me off
